I get the error "Error using griddedInterpolant. The grid vectors must contain unique points"
My script is:
%interpolating modelled at observed depth
for j = 1:length(time_obs)
T_subsurf_mod(:,j) = interp1(depth_act(:,j),T_ice(:,j),depth_obs(:,j));
end
T_subsurf_mod and depth_obs are both 11x8784 double and depth_act is a 201x8784 double.
I have tried using the function "unique" on my input but does not work.

Well, the error message is pretty explicit and seeing your code doesn't really help us with that in any way! What do you mean by using unique 'doesn't work'?

%interpolating modelled at observed depth
for j = 1:length(time_obs)
[~, uidx] = unique(depth_act(:,j));
T_subsurf_mod(:,j) = interp1( depth_act(uidx,j), T_ice(uidx,j), depth_obs(:,j) );
end
